' of my invention. It should be noted, however, that the features which com rise my resent invention may be applies to the e. 6 Remington machine without any structural modification of that machine.

I The truck 1 of the carriage which is adapted to move from end to end of the machine in the usual manner supports a paper table 2 thereon, and has pivoted at each end thereof at 3, a link 4 which sup o-rts at its upper end a in 5 that is adapted to oscillate with the lin between the-adjustable screw-stops 6 that are carried by the truck. The pivot pins 5 pivotally connect the. platen frame 7 to the links 4 and permit a transverse movemerit of the platen frame for upper and lower case writing. The pivot pins 5 are seated a cross-bar 8 which is ri idly secured to or forms a part of the platen frame. This cross-bar 8is provided with supporting ears 9 that have pivoted therein at 10 the arms 1 1, each of which is rovided at its lower end with a hearing 12 or the reception of a shaft 13 on whichthe paper feed rollers 14 are mounted to revolve; suitable spacing sleeves being employed between the rollers to maintain them separated. -Each of the arms 11 has secured thereto at 15 a spring 16 which projects upwardly and bears at its free end against a stud 17 that projects from the cross bar 8, andthe tension of these springs 16 is effective to normally maintain the'pa er feed rollers in contact with the platen. V T e arms 11 are each provided with a bearing stud 18 against which a finger 19 that extends from a rock shaft 20, is ada ted to bear. This rock ort by suitable screw bear ings 21 carrie y the platen frame. Rigidly secured, referably to the left-hand end of the rock s aft, by a set screw 22 is an arm 23 which has a finger iece 24 extending there'- from. The rock sliaft 20 likewise has an arm 25 adjustably secured thereto by a set screw 26 so that the arm may be adjusted around the rock shaft.

The lower end of this arm has a threaded opening which is finger 31 which'is adaptpd'to be projected. through anaperture 32 in a paper apron or scale plate 33, as will hereinafter more clearly Lappear. An arm 25, stop carrier29 and are withdrawn from the apertures 32 and 'tured at '34 to ermit the paper feed rollers 14 paper finger or sto 31 are secured at each end of the rock sha t 20, as illustrated in Fig. 3. The paper apron 33 is likewise aperto be projecte therethrough and into contact with the laten 35 which is revolubly carried by the p aten frame 7 The lower edge of the paper apron 33 which carries the usual scale 33 is maintained in contact with the platen by springs 36, one of which is secured at 37 to each of the arms 1 1 and the tension of these springs is such that the lower edge of the paper apron will be maintained against the platen at all times irrespective of the fact that the lower ends of the arms 11 may be moved away from the platen to carry the aper feed rollers out of contact therewith.

t will be observed from an examination of Fig. 4 that the disposition of the fingers 19, with relation to the arms 11 which are under s ring pressure, is such that the tension of t e spring 16 tends to maintain the rock shaft 20 and the finger piece 24 in a normal position. These parts are limited in their movement to the normal osition by an abutment 38 which is carried by the arm 23 of the finger piece and is adapted to contact with a rigid abutment 39, carried by. the platen frame, when the parts are in the normal position. Themovement of the rockshaft 20 and the partscarried thereby in an opposite direction is limited by the usual locking pawl 20 which is carried by the rockshaft and is adaptedto be forced into contact with the .usualratchet Wheel 35 and thus limit the movement of the parts.

In the normal or operative positions of the parts, the feed rollers 14 are projected through apertures 34 in the paper apron and are in contact with the platen, as indicated in Fig. 1, and at this time the paper stops 31 are maintained away frorn'the platen, as shown in Fig. 2. When, however, the finger piece 24 is moved toward the rear of the machine, it will cause the fingers 19 carried by the rock shaft to bear against the abutments 18 on the arms 11 and to move said arms against the tension of their springs, thereby withdrawing the feed rollers from contact with the platen. During the movements of the partsjust described, the paper fingers 31 will be projected through the apertures 32 in the paper apron and into contact with the platen, as shown in Fig. 4. It will be observed that when the parts are in the position shown in this figure, the paper stops are interposed in the path of the leading end 40 of the pa or 41, which is inserted in the machine, an that these paper sto s provide means by which the paper can e quickly and efliciently'squared or positioned on the platen. As soon as the finger piece 24 is released, the paper fingers 31 will be. Withdrawn from the path of the paper and l fingers to be adjusted so that they may be projected toward the platen to varying extents, though I prefer to adjust the parts so that when the finger piece 24 has been moved in the direction of the arrow in Fig. 3 to its full extent, the paperiingjers will be brought into contact with the platen. This adjustment likewise enables the stops to be. properly alined so that the paper will be squared on the platen when brought into contact with the stops. F urthermorc, the adjustment enables the line at which the paper is arrested by the stops to be varied, so that the paper after it is arrested may be fed to the proper position to begin the first line of writing.

The paper stops of my invention not only aid in squaring orpropcrly positioning the paper on the platen but they likewise insure that the paper will always start to be fee with the platen from the same point and a subsequent actuation of the ordinary line spacing mechanism (after the paper stops are withdrawn and the paper feed rollers are in contact with thepaper) will feed the paper to the proper position to begin the first line of writing. It Will be understood therefore that the device may be used without alteration in connection with a line counting or indicating device of the character shown for instance in the patent to Higham No. 682,870, dated Sept. 17, 1901.

The paper, apron 33 is connected at its upper edge to blocks 42, one of such blocks being rovided at' each end of the apron. These locks are cars 43 by means 0 supported u on the rock shaft 20. Upon reference to ig. 6, it will be observed that the blocks 42 are each transversely recessed at 44 for the reception of a sliding piece or bar 45 which is secured to a paper guide 46. This bar 45 is bent at 47 and forms an extension 48 which is parallel with the bar 44 and is provided with a slot 49'through which the stem of a headed set screw 50 is adapted to pass. The stem of this set screw is received Within a threaded opening in the block 42 and means are thus provided for adjusting each of the paper guides-46 for a limited distance in the direction of the length of the platen. The tightening ,of the screws maintain the guides 46 in their adjusted positions. Each of" the paper guides 46 is formed of an L-shaped plate which comwhich they are movably provided with apertured prises a paper support 51 and an extension or abutment 52 that ektends at right angles 2 5 stances to providebut a single guide near the left-hand side of the platen.

thereto. The angular extension or abutstitutes a support upon which the paper is are adapte adapted torest.

Upon reference to Big. 1 it will be observed that the lane, of the lower, portion of the paper tab e 2 is substantially coincident with the plane ot the portions51 oi the paper guides so that pa er which is placed upon the paper table may e readily fed and guided to the paper guides 46. It will likewise be observed that the paper apron forms a continuation of th'eportions 51 of the paper guides so. that the paper which is received on these portions 51 may be readily guided to the paper apron.

. While I have shown and described the use oil two paper guides 46, which are inde wnd ent of the paper stops but which however,

erly (position the paper, it should be understoo that it maybe suflicient in in st in- It should likewise be understood that while I have described with considerable detail, the separate paper stops or fingers 31, a single bar 53 (Fig. 7) provided with slotted stop carrying arms 29" and which extends throu hout or substantiallythroughout the lengt of 'the platen may be employed in their stead, and if desired, this bar may be cut away at intervals throughout its length as shown at 54% as to provide a series of paper stops 31 From the foregoing description, it will be understood that the paper gage or stops-are independent of the platen and operate forwardly oi the bight of the feed between they feed rollers and platen and are rearwardly of the horizontal scale or paper retainer 33, whicl'i is in the rear otthe printing line, and that the stops are capable oi an up and down adjustment.
